Resultant of three forces about a point O

Click For Summary
SUMMARY

The discussion centers on calculating the resultant of three forces acting on a point O in a two-dimensional space. Participants emphasize the importance of determining the x and y components of each force, followed by calculating the resultant magnitude using the Pythagorean theorem. Additionally, there is a focus on finding the perpendicular and horizontal distances related to the resultant forces, which are crucial for understanding 2-D moments. Clarity in problem interpretation and approach is also highlighted as a key factor in successfully solving the problem.

PREREQUISITES
  • Understanding of vector components in two dimensions
  • Knowledge of the Pythagorean theorem for magnitude calculation
  • Familiarity with the concepts of perpendicular and horizontal distances

My question is to find the resultant just take the x,y components of each force, find the magnitude by squaring them and taking the square root. My question is after doing that how would i find the perpendicular and horizontal distances.

My teacher put a study guide for our test and it said resultant of 3 forces about a point, 2-D, 2-D moments.

Maybe i misinterpreting what he really wants?

The picture is not the actual problem just an example.
